Extracting Data From Closed Workbook

I'm currently facing problem with double for loop in the previous vba ,extracting data from closed book. however, it uses only one for loop to extract all data. I need to extract lots of data from the book and thats why i double looped it to extract more data. however, i can only get the first line of data i can't extract any more data from then on.

Sub RunCodeOnAllXLSFiles()
Dim lCount As Long
Dim wbResults As Workbook
Dim wbCodeBook As Workbook
Dim rCell As Range
Dim lCount2 As Long

Worksheets("Data").Select
Range("a2:ac65536").Clear

Application. ScreenUpdating = False
Application.DisplayAlerts = False
Application.EnableEvents = False
